OIL-LAMP.

SPECIFICATION forming part of Letters Patent No. 275,682, dated April10, 1883.

Application filed January 18, 1883. (ModeL) To all whom it may concernBe it known that I, SAMUEL MAXIM, of Wayne,in the county of Kennebec andState of Maine, have invented certain new and useful Improvements inOil-Lamps, of which the following is a full, clear, and exactdescription.

My invention consists of an attachment to oil-lamps, and particularly tothe tubular lantern, to prevent the escape of the oil from the lamp,which in the case of the said lantern gets into the turret and the tubeson top, making bad smells and being dangerous, and another difflcultywith such lanterns and other lamps is the flickering of the flame, dueto the insufficient supply of air as the oil burns away, which myinvention is calculated to prevent,- all as hereinafter fully described.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional elevation of a burner provided with my improvedoil-catcher, and Fig. 2 is a plan or top view of the catcher.

I extend the tube a, into which the burnertube 9 screws, a suitabledistance into the oilchamber below the shell b of the oil-chamber, andconstruct the lower end of said tube a with a flange or collar, 0, theouter edge of which is attached to the inside of the shell 1), making anannular chamber, d, into which I make a passage, 0, through shell b, andout of which I make a passage, f, into the oil-chamber of the lamp, andI locate these passages on opposite sides of the burner-tube for makingthe course of the opening into the lamp the most indirect and bestcalculated to prevent the escape of oil in case the lamp should beoverturned.

On the top of tube a, I make a flange, h, of suitable breadth, from theouter edge of which a vertical tubular extension, arises about as highas the wick-ratchet stem j will allow, said tube being considerablylarger than the collar k of the lamp-burner. The flange h has a passage,1, into chamber m below, and tube t is surrounded by the outsidecatcher-tube, n, soldered or otherwise fitted oil-tight at its lower endto the shell b, and at the top having a flange, 0, turned inward anddownward over the top of tube 4 and inward again to a closefittingjointwith a lamp-collar, 70, making an annular recess,p, into which any oilthat escapes from the wick and around the ratchetstem, or in any otherway, will drop, and from which it .will pass through numerous smallholes, q, in flangeo to the space 8, from which it will drop throughpassage linto space m, thence passing into chamber 0?, and finally backinto the oil-space, so as to prevent any overflow upon the exteriorofthelamp, also to prevent the escape of the odorous vapor of theoilywhich will not be generated because of the free circulation of airadmitted to the lamp, which, by keeping the oil cool,will materially, ifnot wholly, prevent the escape of vapor. The air thus freely admittedwill prevent the flickering of the lamp, which is .sometimes caused forlack of oil, caused by lack of air, to allow it to ascend the wick-tube.

In the case of a glass oil-holder, the tube a and flange 0 must beattached to the collar that is commonly connected to the top of theoil-holder, said collar being made larger for the purpose, or theoutside part of the attachment must be contrived for connection with thecollar k and the flange c to the burnertube g, which must be attached atits outeredge to said collar.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with an oil-lamp, of anoil-catching attach mentconsisting of the flan ge 0, extending fromthelower end of the tube a,

and fastened to the inside of the shell of the oil-vessel, the flange h,extending horizontally from the upper edge of the tube a, tubei,projecting upward from the outer edge of the flange h, and tube at,having the stepped flange 0, substantially as and for the purpose setforth.

2. In an oil-lamp, the tube a, extended into the oil-chamber, and theflange 0, connected to the said inner extension of the tube, and to theinner surface of the oil-chamber b, forming chamber cl within the oilchamber or vessel, the shell of the chamber b being provided with apassage, e, leading to the chamber 0 ICC) and the flange or bottom 0 ofthe latter having a passage,f, leading to the oil-chamber, said passagesbeing arranged on opposite sides of the tube a, substantially as and forthe purpose set forth.

3. The combination, in an oil-lamp, of the tube 11, attached to theoil-holder b, and having flange o, with the tube a having flange h, I

and vertical tubular extension 1', said flange 0 forming with the collar7; the annular recess p, and said flanges o and it having passages q andl, substantially as described.

at. The combination, in an oil-lamp, of the tube 9, attached to the oilchamber or vessel I), and having at its upper end the stepped flange0,with the tube a of the oil chamber or vessel,

said tube a being extended into the oil vessel or chamber, and having atits upper end the horizontal flange h, flange 0, connecting the lowerend of the tube a to the oil-vessel, and tube 2, extending from theouter edge of the flange h upwardly, said combination of partsconstituting the recess 12 and chambers s, m, and d, said recesscommunicating with the chamber s by a passage, q, and the latter chamberwith the chamber m by a passage, 1, substantially as and for the purposedescribed.
